Independent filmmaker John Sayles wrote and directed this movie from 2007 about a blues club owner (Danny Glover) in 1950 Alabama, who tries to track down a guitar player to perform at his club. It's a look at the very beginnings of rock and roll, which of course came out of the blues music in African-American communities. It's a little known, smaller film, but it boasts a great ensemble cast along with some terrific music, and even has a bit of a spiritual bent to it in the form of a mysterious old guitar strummer who seems to haunt the town and Glover's character. You should seek this one out.
